Feature Request: scroll label ONCE

Is it possible to implement additional label display modes (in addition to LEFT, CENTER, SCROLLRIGHT, etc.) Where the text would scroll once and then just display as many letters of the label as can fit in the alloted area?

I'm thinking of this more for the display of song information rather than anything else. Having a long song title, artist name, and album name all eternally scrolling can get distracting. Ideally the labels would scroll whenever a new song starts playing and then stop (or maybe scroll every 10 seconds?).

Edit: As an aside, would it be possible to implement scrolling by character instead of smooth scrolling? I use a LCD-like font and it looks weird to have the individual characters scroll off the screen rather than disappear one by one.
